I'm thinking about the scenario where you create a branch to do some dev work. It takes a week or so, during which, other commits are happening on master. Probably at multiple points during your week of dev work, you are going to want to pull in updates from master to make sure you don't hit conflicts or run into issues that weren't found until the day you try to merge your final work.

It sounds like you are saying that every time you want to update, you'd create a new integration branch of your work + master and then switch to that for further work until you are finally ready to commit to master? That feels a bit unwieldy..
